Explanation
A network virtual appliance acts like a firewall. It checks all inbound and outbound traffic, and it secures your environment by allowing or denying the traffic.
A is incorrect. A network virtual appliance doesn’t control outbound internet access. This access can be controlled by policies.
B is incorrect. A network virtual appliance doesn’t load balance traffic across virtual machines for DR purposes. Such load balancing is the role of Azure Application Gateway and Azure Traffic Manager.
D is incorrect. To control inbound access to Azure, you would use authentication and authorization policies. Network virtual appliances aren’t used to authenticate users.
